SPECIFICATION fetmtng leert ef Lettere Patent No. 248,577, dated oeteber 25, 1881. Application filed August 6, 1881. (No model.)

To all whom it may concern:

Be it known that I, ABsALoM C. GONERY, a citizen of the United States, residing at Maquoketa, in'the county of Jackson and State of Iowa, have invented certain new and useful Improvements in` Stalk-Cutters; and I do hereby declare the following` to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawand to the letters or figures of reference marked thereon, which form a part of this specification, and in which- Figure l is a side elevation of my improved stalk-cutter. Fig. 2 is a longitudinal vertical section thereof 5 and Fig. 3 is a partial inverted plan with the portion of the machine back of the spring broken away.

This invention has relation to improvements in stalk-cutters, particularly for cutting cornstalks, having for its object to effectthe autoA matic elevation of the cutters by a backward movement of the machine; and the nature of my invention consists in combining with the stalk cutter-cylinder frame certain elevating mechanism, substantially as hereinafter more fully set forth and claimed. e

In carrying out my invention I employ, in connection with the main frame A and the inner frame, A', carrying the cutter-cylinder B, having the transverse critters or blades ct, the parallel rods G U, which pass through apertures in the cross-pieces ofthe frame A. The inner ends of the rods G C are preferably formed with hooks or eyes b, to which the cuttercylinder frame A' is connected by perforated plates, hooks, or eyes c, to form hinge or pivotal joints between the two frames, to enable the cutter-cylinder to operate independently of the main frame and be capable of elevation, as presently described. These rods are encircled between a crossbar, d, and adjusting-nuts d', screwed thereon, by coiled springs E, by which it will be noticed that the pressure of the springs is applied to the rods, so that the concussion of the chopping or cutting action of the knives of the cylinder carried or drawn by the frame A', hinged to said rods, will be received upon the latter and be taken off the mainframe, to which the team is hitched, and upon which the driver stands or is seated. This latter is obvious from the fact that as the concussion is received upon the rods they move, by reason of their spring-bearings, and not the main frame having the drivers seat, and to which the team is connected. The nuts d' permit, also, of' taking up slack from wear of the springs, and the increasing` of the resisting capacity of the springs to promote their efflciency.

F F are two short standards, pivoted or hinged upon the rear part of the main frame A, preferably under cover, and connected together by a cross-piece, F'. This forms a lever, the operating medium of which consists of arod or lever,f, passing forward through the aforesaid cover, or otherwise supported within convenient reach of the drivers feet. A cam,

is arranged upon the shaftf, hung in the standards of said lever F F F', and has passing over it and attached to it a cord, chain, or wire,j`3, reaching down and-connected to the rear end of the cutter-cylinder frame A'. At the ends of the shaft f2 are friction rolls or disks h, which are adapted to bear upon the drivin g-wheels G when the lever F F' is thrown forward by operating the lever t', and as the machine is backed the motion received from the Awheels G will cause the rolls It to revolve, and with them the shaft f2 and its cam f', which will effect the automatic elevation of the frame A'and cutter-cylinder up out of use. The shaftf2, with its cam and the cutter-frame-elevating medium f3, is also capable of manipulation and being held so as to ree tain the cutter-cylinder in its elevated position by means of the hand-lever i, extending forward within easy reach of the driver, when the shaft has been turned so as to elevate the cutter-cylinder.

Having thus fully described my invention, I claim and desire to secure by Letters Patentl. In a stalk-cutter, the combination, with the main frame A and the cutter-cylinder frame A', of the lever F F7 having the came shaft f2, cord f3, the operating mechanism f, and the friction disks or rols IL, substantially and the friction rolls or disks h, substantially as and for the purpose set forth. ro as described. In testimony whereof I affix Iny signature 2. In a stalk-cutter, the combination, with in presence of two witnesses. 5 the main frame A, its wheels G, and the cut- ABSALOM C. CONERY.
